Abstract: The evolution of enforcement infrastructure from legacy compute engines to modern platforms represents a critical challenge in contemporary software engineering environments. The migration of Meta's anti-scraping enforcement platform from the Haskell-based Sigma compute engine to the Omega platform exemplifies the complexities inherent in large-scale infrastructure modernization initiatives. The transition encompasses extensive feature sets and multiple policy endpoints while maintaining zero service degradation and enforcement accuracy throughout the migration process. The methodology employs systematic dependency discovery, comprehensive feature parity verification, and advanced regression validation frameworks to ensure seamless platform evolution. Proactive observability mechanisms and staged rollout strategies guarantee system reliability across high-volume production environments processing billions of daily transactions. Advanced dependency analysis tools enable identification of hidden system interconnections while automated testing frameworks validate functional equivalence between legacy and modern implementations. Performance optimization techniques demonstrate substantial improvements in system scalability and operational efficiency following migration completion. The comprehensive validation framework successfully preserves institutional knowledge while enabling future platform enhancement capabilities. The successful implementation establishes effective practices for de-risking infrastructure evolution while maintaining enforcement efficacy in mission-critical production environments.
